Ive been shooting IR with a borrowed a100 so my time with it is limited but ive made some progress with my own experimentation. now i am at a stumbling block oping for some one whos shooting it as well with the a100 or other camera that has exhibited simular issues can help.
using the a100 with the kit lens (18-80) and a hoya r72 IR filter. was getting nothing first, played with some settings after researching the subject, and results were better but nothing like i see on web galleries etc... I know ALOT of post process work goes into them but tutorials showing it have way better beginning images to work with.
my meter reading is TTL, but its WAY off. usually 6 or 7 stops. In bright sunlight im still having to use 2 sec (or more) exposures at ISO's of 100 and 200.even shooting wide open to get a useable (barely) pic but my meter said it wanted something more like a 1/125... not a big deal except that vegetation is blurry every time due to wind. most stuff im finding says it should be 1 or two stops off of your meter at most.
even with the above, the red hue is so dark that almost no detail is visible until deconstructing image in PS. I also set custom white balance with a shot of grass, which is better, but still so much cyan its not any easier to PP than the red images. (usually shows on display around 4000k as temp, is this what you all are getting?). Ive turned off dro, turned on dro+ etc and my overall experience is that no matter what i do, my shots are way underexposed.durin PP work when i use the channel mixer to swap out and return the sky to blue etc for color ir, its just doesnt seem to work (although its likely this could be my PS skills)as well as the tutorials. when i seperate the channels, my red is the best one, with green being almost unuseable and blue so underexposed that no detail remains basically. while this isnt a huge problem with a b&w pic, the underexposure combined with the long shutters im needing are really making the noise. a couple of pics this could be cool, as it looks like ilford 3200 film prints etc and have a nice old school look, but I also want razor sharp and this is no way to get it. I know how to handle the camera and get good results normally, this is just getting frustrating (kind of like the 2 rolls of film ir I shot way back when that led to my not pursuing it then, at least now its alot cheaper!)and no matter what ive done on the 4 occasions I have had to shoot has produced a result of printable/display quality. any advice helpful and appreciated thanks...
